While you might not need to manage
as many as 25,000 accounts, it's nice to know that MailBurst supports as many
users as you need. When a new user asked about managing a system with 25,000
users to distribute mail to 2 dozen POP3 servers. We told them "Sure" and even
version 1, released in September '96 would be up to the task.

Wild card forwarding *@domain1.com
to *@domain2.com (mail sent to david@domain1.com and ben@domain1.com
are forwarded to david@domain2.com and ben@domain2.com respectively)

A simple text-based config file
for users who wish to generate their configurations automatically using
databases, scripts, or CGIs

Facilities to Bounce and
Trash incoming mail to certain addresses (e.g., simply trash all mail
coming in to unknown addresses... no need to bounce back to SPAMMERs who don't
exist, generating even more email.)

Save messages to disk (lets you
archive a copy of every message to an address and at a later time re-send
them again -- handy when people need to temporarily re-route mail to a web-based
mail account and when they return send again to a normal POP mailbox)

Built-in testing

A Drop-box
folder to support sending e-mail with CGIs and other software (simple
format to generate a single message to many people or totally custome email
messages on the fly with NO network overhead to hand off the message to EIMS
or SIMS).

Ability to reject a message if
the size is greater than a specific amount (set for each incoming address)

Support for group file lists for
unlimited numbers of recipients (similar to the MailBurst:drop folder)

Detailed log files

Automatic error reports via email

Industrial strength performance
and reliability (version 2.1.2 has been stable since August, 1999. Version
2.1.3 was introduced in May, 2001 to add group files)

Below is a link to of each of the
major screens in the program and more detailed information. The program is very
simple and the GUI makes it easy to add new accounts, set up multiple destinations
and set up features like auto-replies.

You will find the detailed info
